These High Output injectors by Unlimited Diesel were designed to produce the maximum amount torque capable for heavy towing applications, utilizing stock components. The AD/30's utilize a 30% over stock output nozzle to allow the fuel to enter the combustion chamber faster, producing a cleaner and more efficient burn rate. These injectors retain the factory split shot plunger and barrel, so no additional tuning is required to run them. These injectors are perfect for someone wanting a slight increase in horsepower without installing a tuning device, in 1999.5-2003 Trucks (Built After 12 07 1998 7.3L).

If you have a chip already, depending on manufacturer, you could notice power gains in excess of 380hp with these injectors.
